I bought these from Golden Tee for my Suzo Happ trackball. They work great right out of the box. They also have easy-to-remove screens for easy cleaning and re-lubrication when needed. I use mine with 3 in 1 oil and I have another set with Bones Speed Cream. These bearings are very smooth running and have the highest Abec rating (abec5) that you can achieve without using hybrid or full ceramic bearings. I would highly recommend anyone with a Suzo Happ trackball to try these bearings and you will not be disappointed. Edited to include product image. They come exactly as pictured on the first stock. I've included another bearing with the shield removed and shown what the shield and C-ring look like removed. You can remove the shield from either side of the bearing and easily put it back together.
